   template< class I1, class I2, class Comp,

             class Proj1 = std::identity, class Proj2 = std::identity >
   concept indirectly_comparable =                                        \fI(since C++20)\fP

       std::indirect_binary_predicate<Comp, std::projected<I1, Proj1>,

   The concept indirectly_comparable specifies the fundamental algorithm requirement
   for comparing values across two independent ranges.

   Semantic requirements

   indirectly_comparable is modeled only if all concepts it subsumes are modeled.

                             specifies that a callable type, when invoked with the
   indirect_binary_predicate result of dereferencing two indirectly_readable types,
   (C++20)                   satisfies predicate
                             (concept)
